I will now" describertberloading operationr of the loader: When-the scoop is'-located at theextreme-lowerendof the raiL-seetiont; as illustratedzinFigure- 4,- thesweightofrthe scoop will tilt this :section: to a -verticalposition. -A-cable 2E) is unreeledi from the hoisting/e device 2|; through the sheave 22, which isejournaleda to the cross shaft 23, mounted within-t the. inclined framed;- The cable-thenpasses throughcthe sheave .24; whichds j ournaled within the end: of. the A- frame- 25, thence over-the -sheave zewhich is journaled to the crossshaftllmounted within- .the frame 42 Thercable 1 then runs through the-sheave which is journaled to the cross shaft 29, alsocmountedit the-eframes lfla Fromthesri eave 28'the, cable-passes:through the sheave fill mounted to the-crosslshaft it within them! nor end of the sub-frame ll of the railsectiorril. After the cable passesothrough the sheave :31}; it is fixedly secured-to the scoop l4--at'-32. When the cable 2% ,is;slacked. ofiflfrom the:hoistingdef VicelZI, it will permit the rail sectionsa-andits subsframe, I I to pivot .about the cross shaft [2 bythe weight of the scoop ,I 4, bringinglthe scoop to loading position. An Aeframe v33 is .pivotally mounted. to the cross, shaft I 2 at its upper end and is. held slightly at an incline .toithe vertical by acounterweight 34.. Asthe scoop'l4 is lowered a stop-.35,.1formingupartof the scoop, engages the end 35=of theA frame 33. I V

When the truck I. isbackedlunto the pileof material .to lbelscooped. into thescoop. M, and thehoisting device ,2! isvcaused to pull the cable. Ell over the-sheaves above'described, it will pivot the rail section 8 about, theshaftv lz} bringing the lip, 3'! 'of the. scoop l intoengagement with the material "tobe scooped. TheA-frameiis will maintainth'e scoop at. the outer endoi the rail section B'untll the scooplha's been filled, at, which time the trip chain 38 will disengage the end 36 of the A-frame from the stop 35; allow-- ing the cable 20 to pull the scoop alongthe'rail section 8 until it passes the pivot point i. of the rail section, at which timeit'will lower the end 39: into alignment with therail. section 9; b'est' illustrated in Figure 1. The scoop continues to be pulled over the rail section 9 and on to the rail section II). The rail section is pivotally mounted to the inclined frame 4 upon the cross shaft 29. The end 40 of the rail section II] is held down by the locking bolt 4| which is slidably mounted along the edge of the rail 42 within suitable guideways 43. A spring 44 maintains the locking bolt 4| under the ball of the rail 45.

The reason for locking this section down will now"be described. The A-frame 251 is pivotally mounted to the sub-frame 46 of the rail section H! by the cross shaft 41.

the rails, but when the scoop arrives on the rail section II) it is then desirable to tilt the scoop as illustrated in Figure 5.

Referring to Figure 2, when the scoop has arrived at a given position upon the rail section I0, 2. stop 48,'forming part of the scoop engages the turned up "arm 49, forming part of the locking bolt 4|. This engagement will cause the locking bolt 41; to be disengaged from under the ball of the rail, therefore when the wheels l5 engage the stop 50, which is fixedly mounted to the rail section 10, the cable 20 will raise th A-frame 25 to the'position shown in Figure 5 thereby dumping the scoop. When the scoop has been dumped the cable 20 will then be slacked off allowing the A frame 25 tolower' the frame section H), which will their be locked by the locking bolt 4| to the rail 45; The weight of the scoop will then cause the scoop to move to the loading position by gravity along the inclined rail sections as heretofore described. The scoop is prevented from travelling beyond the end of the section 8 by the stop 5 l' engaging the wheels [5. I Th hoisting device 2| may b of any suitable design having 'the usual braking mechanism 52 and clutch mechanism 53 for controlling the same, and a driving connection 54 driving from any suitable power take off relative to the truck. I do not wish to be limited to the exact mechanism 7 herein shown and described, as other This fram 25 receives an end thrust from the cable 20 through,.the, sheave 24 when the scoop is being moved along gravity when the scoop is in predetermined position on the loading sections of the rails to lower the scoop into a loading position, and a locking member movably supported on the tilting frame and automatically operating with the scoop when the latter is in loading position to prevent movement of the scoop in one direction.

5. A construction as defined in claim 1 wherein a tilting frame is mounted to carry the loading sections of the rails and wherein said frame is tilted when the scoop is at one end of the loading sections of the rails and wherein a cable is provided to move the scoop lengthwise the loading r'nech'anical equivalents maybe employed still coming within the scope of my claims.
